Leader Accessories Pop Up Folding Camper Cover RV Trailer (12'-14') - Waterproof UV Protection for Outdoor Camping & Travel

We have this cover on our pop up camper that sits out in the harsh WI winters. So far so good. Stays on great when it's windy. One person can put it on but two people make it much easier.I bought this cover for an Aliner Classic, which has a 12 foot box and is 15 feet long, hitch to bumper. I had some trouble deciding if I wanted the 10-12 or the 12-14 cover. From other reviews, I guessed the 10-12 would fit and cover my spare, mounted on the bumper. I also wanted to cover the tanks and battery on the front. I wasn't sure if the 10-12 would go that far. So I ordered the 12-14.As you can see from the photos, the 12-14 does all that with material to spare...probably 2 feet to spare.The materials and construction appear to be good to my untrained eye. Installation was easy, even with minimalist instructions. I did it by myself, without any ladder or step stool (even though the trailer is parked on a sloping surface.) I did take the time to use blue painters tape to affix rags over the sharp corners on top. Installation would be more of a challenge on a windy day. Still, it is far better than a tarp and bungee cords.I primarily wrote this to assist other owners of Aliner Classic trailers in deciding which size to order. Next time, I will try the 10-12 size cover.I plan to amend this review once time and weather have taken its toll on the cover.Fits like a gloveA grat well made cover at a fair priceA few reviews of similar products had me doubting the size. Fit perfect on my AFrame camper. Not sure about durability but seams well made.Fits our Rockwood A-Frame (15-footer) just fine; was a piece of cake getting it on camping trailer, looks pretty darn good also. Really like the three underneath tie-down straps.3.5 stars.I will upgrade as seasons pass.This cover is made of heavy duty duffel bag canvas. How it will fair in strong summer UV is the big question. Also, it does not seem to be water resistant, so don't expect dryness underneath...but I don't really know as it hasn't rained.Other car covers that I own, which are made of slick shiny reflective material (umbrella or tent slick type material), has held up for a few years, so this product's canvas material is an unknown.Fits a 10’ box with roof AC. Covers spare, LP tank, and battery box. Seems to be of good quality.
